Non-magnetic tweezers in Ni-Cr-Mo superalloy, comparable to Taxal quality. The Boley Superalloy Tweezers are six times harder and more resistant than conventional non-magnetic stainless steel tweezers. Features: – Nickel-Chromium-Molybdenum (Ni-Cr-Mo) superalloy – excellent/resistance to room temperature up to 800°C – 100% non-magnetic and even six times harder than antimagnetic stainless steel tweezers – resistant to fatigue, very high shape retention – excellent corrosion resistance to most chemicals, salts and acids – comparable to Taxal quality Type: No. 4 Execution: very fine, for hairsprings Length: 110mm
